描述了一种基于稀土掺杂重金属氟化物玻璃的两步双频上变频的三色固态体积显示器。该装置使用红外激光束，在有源光学材料的透明体积内相交，通过连续的两步共振吸收来定位红、绿、蓝体素。三维线框图像、表面区域和固体是通过扫描材料内部周围激光的交点来绘制的。该原型装置由激光二极管驱动，使用传统的聚焦光学和机械扫描仪，在室内环境照明条件下也足够亮。
A three-color, solid-state, volumetric display based on two-step, two-frequency upconversion in rare earth-doped heavy metal fluoride glass is described. The device uses infrared laser beams that intersect inside a transparent volume of active optical material to address red, green, and blue voxels by sequential two-step resonant absorption. Three-dimensional wire-frame images, surface areas, and solids are drawn by scanning the point of intersection of the lasers around inside of the material. The prototype device is driven with laser diodes, uses conventional focusing optics and mechanical scanners, and is bright enough to be seen in ambient room lighting conditions.
